Solution Overview

Problem

Patients unable to communicate their height due to unresponsiveness or unawareness pose challenges in prescribing accurate medication dosages, especially when vertical measurement is not feasible.

Innovation Solution

A height-measuring bed sheet with an integrated height-indicative pattern that allows for non-invasive height measurement while the patient is in bed, enabling the determination of proper medication dosages based on height.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional vertical height measurement methods are used, then accurate height data can be obtained, but the patient must be able to stand and communicate their height

Engineering Contradiction:
Improveheight measurement accuracyVSAvoidmeasurement accessibility
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

Instead of measuring height vertically by having the patient stand, the patent inverts the approach by measuring height horizontally along the bed sheet. The patient lies supine on the bed sheet with height measurement indicia printed horizontally across it, allowing the healthcare provider to measure from the patient's head to heels along the horizontal plane of the bed sheet, thus obtaining accurate height data without requiring the patient to stand or communicate.

Inventive Principle:
Principle #13The other way round (Inversion)

2Ease of operation

If the patient remains in bed for measurement, then accessibility is improved, but traditional measurement accuracy may be compromised

Engineering Contradiction:
Improvemeasurement accessibilityVSAvoidheight measurement accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The bed sheet serves as an intermediary tool between the patient and the measurement process. By printing height measurement indicia directly on the bed sheet, it becomes a mediator that enables accurate height measurement while the patient remains in bed. The bed sheet's horizontal measurement scale acts as an intermediate reference system that translates the patient's body length into accurate height data without requiring vertical measurement or patient communication.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If height measurement indicia are added to the bed sheet, then measurement capability is improved, but the bed sheet design becomes more complex

Engineering Contradiction:
Improvemeasurement functionalityVSAvoidbed sheet design complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The bed sheet is designed to serve multiple functions: it provides the traditional bedding coverage function while simultaneously serving as a height measurement tool through integrated height measurement indicia. By combining these functions into a single device, the patent eliminates the need for separate measurement tools, making the bed sheet universal enough to handle both comfort and measurement needs without significantly increasing complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)
